Exposure to typical persistent organic pollutants from an electronic waste recycling site in Northern China
چکیده انگلیسی

Human exposure to pollutants from e-waste is an important scientific issue for their health effects. In this study, organohalogen pollutants in human serum sample from an e-waste dismantling site (n = 35) and a control site (n = 21), both located in Tianjin, Northern China, were analyzed using GC–ECNI–MS. Geometric mean concentrations of tetra- through hexa-BDEs, hepta- through nona-BDEs, PCBs, PBB-153, and DP in the exposure group were 2.77, 12.2, 44.1, 0.52, and 7.64 ng g−1 lipid, respectively, which ranged from 1.5 to 7.4-fold higher than those in the control group through multivariate regression analysis, indicating that working and/or living in the e-waste site was associated with elevated body concentrations of these pollutants. Pollutants with low vapor pressures (i.e., hepta- through nona-BDEs and DP) were at significantly higher levels for e-waste dismantling workers than for local residents living around the e-waste site, suggesting higher exposure to these pollutants might exist for the occupational workers.


► We measured organohalogen pollutants in human serum from an e-waste site unreported.
► Multivariate regression was applied to explore influencing factors of exposure.
► Elevated exposure to most pollutants was associated with imported e-waste.
► Local residents suffered equal exposure to relatively high volatile pollutants.
